The HMRC registration process is straightforward; you’ll need your business/trading name, National Insurance number and UTR (Unique Taxpayer Reference) number. Your UTR number is 10 digits long and unique to every UK taxpayer. If you don’t have a UTR number you’ll need to register for self-assessment first, HMRC will then issue you with one. Your payment provider will then use this to verify your details with HMRC.
